Call of the Ravens
Talisman of Wizard Eye
A living eye peers out of this bloodstone amulet, looking this way and that. The eye (which is quite hard like a pearl) can be taken out and placed somewhere. The wearer of the amulet by concentrating can see through the eye. They can make it look around but it cannot move.
Found in a bottle in the mine, Kalamar was able to discern its purpose and now wears it around his neck tucked out of sight within his robes.
